Hi, I made an assistant and hooked it to a phone number I bought directly through VAPI. Almost at random, at some point throughout the conversation, I heard a loud honking-like sound on the assistants end. That sound appeared always at the same time stamp. The problem was magically fixed by changing slightly the assistant's greeting, but I sometimes get that same random bug. I've bought a second number to see if the number was the problem, but it persisted with the other number. Call IDs: - fcf3b5cd-2b31-482b-9069-001a3aa629cd - ac746454-fadb-426a-9f70-359c1b98c9ac - 33623c7a-cd3e-4628-b744-624661df1a88 (This one is on a different day. The sound was at the 50s mark) https://cdn.discordapp.com/attachments/1250514644464963594/1250514644573884468/fcf3b5cd-2b31-482b-9069-001a3aa629cd-1718133508928-79693ff5-d91f-42d3-9445-970620321460-mono.wav?ex=666b3804&is=6669e684&hm=9026fcb1058a7b7f61d49363c6a4a8118c98786ef3e7c39723a8872c08c20619&

@Vapi sure. I only changed the name of the assistant (in the greeting message) from Juliana to Julia, and the sound magically disappeared. Also, I've noticed that the sound isn't there when I talk to the assistant through the playground. Only when I call the physical number

@eitansprejer It's quite intriguing that a simple change in the greeting message, such as altering the name from Juliana to Julia, resolved the issue temporarily. This suggests that the problem might be related to the text-to-speech (TTS) synthesis or the audio streaming process over the phone network, rather than the assistant's core functionality, since it doesn't occur in the playground environment. Given that the issue is specific to the phone interaction, it could be a glitch in the TTS engine when processing certain phonetic combinations or an encoding issue when the audio is transmitted over the phone network. To help you further, I would recommend the following steps: 1. Document the exact greeting messages used when the issue occurs and when it does not. 2. Note the times and conditions under which the issue appears and disappears. 3. If possible, try using a different TTS voice or adjusting the speech rate to see if the issue persists. Since the problem is not present in the playground, it might also be beneficial to compare the audio encoding settings between the playground and the phone system. If the issue continues, please provide the additional details I've requested, and I will ensure that our technical team investigates the call IDs you've provided. They will look into the audio streams and system logs to identify any anomalies at the 50-second mark or any other patterns that could explain the honking-like sound. Your patience and cooperation in this matter are greatly appreciated as we work to resolve this issue for you. If you have any more information or need further assistance, please don't hesitate to let me know.
